AND SOME OTHERS..
4. int f(int *a)
{

6.
void f(int i)
{
int j;
for (j=0;j<16;j++)
{
if (i & (0x8000>>j))
printf(“1”);
else
printf(“0”);
}
}
what’s the purpose of the program
a. its output is hex representation of i
b. bcd
c. binary
d. decimal
7.#define f(a,b) a+b
#define g(a,b) a*b

}
what’s the value of m
a.70
b.50
c.26
d. 69
8.main()
{
char a[10];
strcpy(a,””);
if (a==NULL)
printf(“\a is null”);
else
printf(“\n a is not null”);}
what happens with it .
a. compile time error.
b. run-time error.
c. a is null
d. a is not null.
9. char a[5]=”hello”
a. in array we can’t do the operation .
b. size of a is too large
c. size of a is too small
d. nothing wrong with it .
10. local variables can be store by compiler
a. in register or heap
b. in register or stack
c .in stack or heap .
d. global memory.
11. average and worst time complexity in a sorted binary tree is
12. a tree is given and ask to find its meaning (parse-tree)
(expression tree)
ans. ((a+b)-(c*d)) ( not confirmed)
13. convert 40.xxxx into binary .
14. global variable conflicts due to multiple file occurrence is resolved during
a. compile-time
b. run-time
c. link-time
d. load-time
15.Two program is given of factorial. one with recursion and one without recursion . question was which program won’t run for very big no. input because
of stack overfow .
a. i only (ans.)
b. ii only
c. i& ii both .
c. none
16.
struct a
{
int a;
char b;
int c;
}
union b
{
char a;
int b;
int c;
};
which is correct .
a. size of a is always diff. form size of b.(ans.)
b. size of a is always same form size of b.
c. we can’t say anything because of not-homogeneous (not in ordered)
d. size of a can be same if
